Y., a corporation of Virginia Application May 12, weasel-m1 No. 610,743 Renewed September 25, 1933 '7 Claims. (01.242-76) This invention relates to that. type of machine in which heavy paper rolls are supported and moved to adapt them to deliver the paper to a newspaper printing press. This invention is an improvement over my prior application Serial No. 513,931, filed February 6, 1931.

The principal objects of this invention are to supply a paper roll supporting reel with ends or spiders for supporting the web rolls, which are power-operated longitudinally, with means for unclutching the power-operated means which operates one spider so that the other spider may be moved independently; to provide this disconnecting means on each spider so that either one may be disconnected and the other operated, whereby a single motor can be used for shifting the spider to accommo-' date rolls of different widths and also to shift the whole roll, thus doing away with synchronizing two motor-operated screws, and to provide means operating through the path travelled by the paper roll when it is in place for preventing the unclutching of either spider while the rolls are being car'riedin the reel.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which 7,

Fig. 1 is an end view of an ordinary paper roll reel with a preferred embodiment of this invention applied thereto;

Fig. 2 is an elevation of the same;

Fig. 3 is a plan showing one, spider connected and the other disconnected;

Fig. 4 is a sectional view on a vertical plane of the means for operating one of the connecting and disconnecting cams; g

, Fig. 5 is a plan of the cam as indicated by'the arrow 5 in Fig. 4;

Fig. 6 is Fig. 5;

Fig. '7 is a View similar to Fig. 5 in an open position, and

Fig. 8 is a sectional view on the line 8-8 of Fig. 7.

The invention is shown as applied to the type of reel comprising a pair'of pedestals 10, which support bearing boxes 11 for the central shaft 12 of the reel. Preferably on one of the spiders is provided a worm wheel 14 directly-connected to the operating motor 13. This worm wheel is secured to the end of oneof the bearings 11 and provides rotation of the reel so that the rolls may be brought into operative position for delivering the paper to the pressas desired. The bearshowing the cam a sectional view on the line 6 -6 of ing boxes 11 are mounted free to rotate in bearings on the pedestals and to them is secured the main shaft 12-.

The bearing boxes also provide bearings for a single screw 15 which extends longitudinally of the reel. Supported by one of the boxes 11 is a on the shaft 12 but are held in proper angular relationshiptherewith by a full length feather 19.

These spiders are adapted to be connected with the screw 15 formoving them back and forth. Both of them can be moved in the. same direction for side register and either one of them may be moved separately from the other for taking care of rolls of different widths.

I and they are mounted free to slide longitudinally Each spider is provided with a cam 20 which has a stud 21 providing a bearing for itself in the spider and it has an arm 22 pinned on the free end of its stud. On the end of this arm is an operating handle 23. The cam 20 is provided with two eccentric slots 24 into which project a pair of rollers 25 supported by a pair of half nuts 26. The turning of these handles 23 consequently will turn the cams so as to bring them into either of the positions shown respectively in Figs. 5 and 6 and in Figs. '7 and 8. In the former the half nuts engage the screw 15 and in the latter they are separated from it. When both of the pairs of half nuts 26 are in the position shown in Fig. 6, the rotation of the screw 15 will move both spiders one way or the other to secure side register. When it is desired to shift one spider, the handle 23 on the other side is operated to move the half nuts into the position shown in Figs. 7 and 8, thereby releasing these half nuts from the screw. Now, obviously the rotation of the screw will move only one of the spiders. This is done for the purpose ofbringing the reel into condition for receiving the rolls and particularly for receiving rolls of a difierent width from those that have been used previously. Thus either one "of the spiders can be moved in either direction so that the proper relationship between the two spiders may be obtained. I

As is customary in structures of this kind, two

limit switches 27, located in series with the circuit that supplies the motor 16 with power, are provided to prevent damage to the machine if either of the spiders is brought too close to its pedestal.

In this way it will be seen that the construction is simplified as only one motor for operating the spiders is used and only one screw, both for obtaining side register and to accommodate the reel to rolls of different widths. Also this eliminates the necessity of synchronizing two motoroperated screws. and operate the cams operate through the path occupied by the paper roll when it is in place. This prevents the unclutching of either spider while the rolls are being carried by the reel. I

'It will be understood that while the reel itself is rotating, both sets of half nuts are closed on the screw so that there will be no change in the actual or relative positions of the two spiders, the motor 16 at this time being disconnected from the power.

Although I have illustrated and described only one form of the invention, I am aware of the fact that modifications can be made therein by any person skilled in the art. Therefore, I do not wish to be limited in this respect, otherwise than as set forth in the claims, but what I do claim is:

1. In a supporting device for a plurality of rolls, the combination of a rotary shaft, means, rotatable with but movable along the shaft, for supporting the rolls, a motor rotatable with the shaft, and means for moving either or both supporting means from the motor.

2. In a supporting device for rolls of sheet material, the combination with a pair of spiders for supporting the rolls and a shaft to which the spiders are connected to rotate with the shaft, of means extending along the shaft and connected with the spiders for moving the spiders simulta neously, and means for disconnecting one of the spiders from said means, whereby one still connected can be moved to change the supporting device to support rolls of different widths.

3. In a supporting device for web rolls, the combination of a pair of pedestals, a shaft supported by saidpedestals and mounted to rotate, a pair of roll supports carried by and rotatable with said shaft and. movable therealong, a single motor mounted to rotate with the shaft and having means for moving said roll supports axially, and

The handles 23 which control means for disconnecting either one of said roll supports from said moving means for the purpose described.

4. In a web roll supporting device for a printing machine, the combination with a pair of pedestals and a shaft supported thereby, of a pair of spiders connected with the shaft to rotate therewith and movable axially with respect thereto for directly supporting the web rolls, a motor mounted to rotate with the shaft and having a pinion on its shaft, a screw supported to rotate bodily with the first-named shaft and having a gear meshing with said pinion, and disconnectible nuts for each spider for connecting it with, or disconnecting it from, the screw.

5. In a reel for supporting web rolls, the combination with a main shaft and its two spiders, said spiders being rotatable with the shaft and independently movable along the shaft, of a screw extending along the shaft, a nut on each spider, said nuts being divided separably so that the parts thereof can move toward and away from the screw to connect the spider with the screw or disconnect it therefrom, a projection extending from each of the nut sections or parts, and a handoperated cam on each spider having means for operating the nut sections through said projections to connect or disconnect the spider with the screw.

6. 'In a reel for supporting web rolls, the combination with a main shaft and its two spiders, said spiders being rotatable with the shaft and independently movable along the shaft, of a screw extending along the shaft, a nut on each spider,

said nuts being divided separably so that the parts thereof can move toward and away from the screw to connect the spider with the screw or disconnect it therefrom, and a hand-operated cam on each spider having means for operating the nut sections to connect or disconnect the spider with the screw.

'7. In a reel for supporting web rolls, the combination with a main shaft and its two spiders. said spiders being rotatable with the shaft and movable along the shaft, of power operated means for moving the spiders along the shaft and individual means for disconnecting each spider from the power-operated means such that the disconnecting means operates, when disconnected, through a path normally occupied by a web roll.
